TIRE-REPAIR PATCH.

Application lcd July 26, 1928. Serial No.. 295,410.

lThe present invention relatesto tire repair patches or blow-out patches which are formed of several la ers ofl fabric, cord or square Woven, and ru ber and which are in- 5 tended to be secured to the inside of a tire easing over the'punctured or broken portion of the tire. These p-atches are Vshaped in arched or curved form so as to fit within and conform to the inner surface of the tire casing and arev coated on their outer or convex surfaces with a heavy sticky rubber cement so that they will adhere to the` interior of the tire casing. i'

It is customary, in lmarketing :these articles, to cover them with a layer of muslin,

holland or transparent paper to protect the sticky surface from contact with other -objects and to preserve the sticky surface, but

'lit necessarily follows that much of the essential and valuable sticky qualities of the patch are lost orabsorbed kby the protective layer which results either in the initial provision p .of a less sticky coating or in the loss of much of the valuable properties of a highly adhesive coating. f

It is the object of the present invention to construct a new article of commerce in which the necessity for the protective covering is obviated so that a highly adhesive coating or surface may be provided upon the surfaceof the patch which `contacts with the interior of the tire casing, 'and4 a much iinproved patch is obtained. The present invention does not interfere with the packing of the article for shipment, ybut facilitates kthe packing and assembly of the article.

It is also an object of the invention to incorporate in theL patch a block of rubber which may be used to plug a rent or tear in the casing and to utilize the block of rubber to assist in holding the patch in its condition and preventing contact of the surface of the patch. A

These and other objects will be apparent from, the description and drawing forming a part hereof, but it will be understood that the showingis merely for the purpose of explaining the invention to those skilled in this art and is not to be taken as limiting the invention to vthe exact details, for changes and modifications may be made in the invention without altering the essential features thereof as set forth in the claims.

In the drawings in which the preferred form of the invention is shown:

Figure l is a side elevation of the iniproved patch;

Figure 2`is an edge elevation; 'I y Figure 3 is a `cross section on the line 3-3 of Figure l.;

Figure 4f is a plan view of the patch ready for application to the tire,

Figure 5 Figure 4;

Figure 6 is a section through afcarton with twonof the! patches assembled therein; and Figure 7 is a section on the line 7-7 of Figure 6.

The patch, except as particularly noted herein, may be of any preferred or known form, that illustrated herein Abeing of the usual or standard construction. It consists of a body l composed of a plurality of plies of cured rubberized fabric'l, l, l0 and l, which are of progressively smaller areas, the edges of the plies or layers being skived off as shown to provide the entire patch with beveled or feathered edges. The patch is vulcanized and'arched both longitudinally and circumferentially to' enable it 'to it against the inner surface of a tire easing, the smallest layer of the patch being placed on the outeror convex side thereof.y The convex surface of the patchy is treated with a heavy adhesive coating 2 byA which the patch may be secured to the interior surface of the tire.

The patch, when assembled in the commercial formv to be sold, is bent or folded inthe reverse directionv to the natural curvature it would assume as manufactured rand `the patch is secured in that position by means of a temporary fastener or binder Various forms of binders may be employed', but they most satisfactory one for the purpose has been found to be 'a light wire staple which is a section on the line 5-5 of is passed through the thin outer edges of v the patch tok secure the patch in reverse curvature. In this position, the patch is held with the sticky coating Qon the inside of the patch. so that it will not come in Contact -with any other surface and thereby its effeccontact. For the purpose of supplying` this bridOe the )referred form of the iiwention its edges to the sticky surface ofthe patch.

In makin g' certain types of repairs, the block of rubber Vis placed over the rent or punc` ture in the tire casing, the heat of running on the road servin` to melt the rubber of this block and causing it to fion into the ruptured portion of the casing. ,t i

Then the device is to be used, the motorist or repairlnan tears the patch apartat lhe fastener 3 or removes the fastenerv and also ren'ioves the bridge piece 5. The patch `can be readily turned inside out asshoivnin Fig* .ures 4; and 5 and applied to the casing' with the sticky or adhesive surface against the interior surface of the casing'. i i,

` The patch as assembled does not interfere With the packaging ofthe article as tivo of the patches can be placed in staggered Jrelation within a carton l0, as shown in nlligurcs 6 and 7.` f y It will be seen that there is provided a new and useful article of commerce, in which the patch is. constructed and assen'ibled so that the sticky or adhesive surface of the patch is always protected and yet is not subjected to deterioration.dueto the presence of a protective cloth or t wrapper.

What is claimed is 1;. A bloV-out patch of rubber and fabric of arched form having an adhesive coating uponitsi normally curved surface, said patch being inverted in curvature so that the adhesivo face of the patch is Within thepatch, anda temporary fastener to hold the ,patch in its inverted form.

, 2. A blow-out` patch of rubber and fabric of arched form having an adhesive coating` upon its normally `curved surface, saidpatch being` inverted in curvature so that the adhesive face of the patch is Within the patch, and means for holding` the patch in its inverted form untilr ready for application to the tire. v Y t 3. A patch for the repair of tires comprising a body having` a coating` of adhesive upon one surface, the body being folded. `so

that the coated surface is entirely within the body and protected solely bythe body, and a temporary retaining` member to hold such patch in the form stated until ready for use.

\ 4. A blow-out patch composed of layers of fabric coated with rubber, said patch being` rvulcanized in arched. form, a layer of ad- .hesive upon the normally convex surface of the patch, the patch being,` inverted for ship* mentyor saleso thatr the normally convex surface isvvithin the invertedpatch and protected solelyby the body thereof, and means to hold the patch inl such inverted form until used. i y i i '5..A blow-out patch composed of layers of fabric coated With rubber7 lsaid vpatch beingrvulcanized in arched form, a layer of adhesive Vupon the normally convexV surface of the patch, the patch being,` inverted for shipment or sale so. that the normally convexsurface is Within Athe inverted patch and protected solely by thebody thereof, and aavire staple passed through kthe edgesj of said patch to'hold it in inverted form.

G. A blow-out patch composed of layers of fabric` coated with rubber, said patch being;` vulcanized inA arched form, a layer Vof adhesive upon` they normally convexsurfaccof the patclnthe patch beingl inverted for shipf i .ment orsale `so Vthat the normally convex surfaceis Within the inverted patch and protected solely by the bodyxthereof, umeans to hold thcpatch insuch inverted form until used,y and a brace extending across -the inverted Ipatch from side to side thereof.

, 7. A blow-out patch composed of :layers of fabriccoated `With rubber, said-patch being vvulcanized inarched form, a layer offardhesive uponthenornntllyV convex surface of the patch, the patch being invertedv for shipment-or sale soit-hat `the normally convexsurfacelis Within therinvertedpatchl and protected solely by thebody thereof, `means to hold the patch in'suchlinverted form until used, and a `block of uncured rubbery adher-` ingmxtV its edges to the surfaces-of the invert-ed patchandf operating as 'a brace to prevent ,eollapseof thepatch.
